END- CLOSING AND PROTECTING MEANS FOR FABRIC ROLLS Filed Dec. 29. 192'? Patented June 24, 1930 JENS E. NIELSEN, OF CHICAGO, ILLINOIS Application filed December 29, 1927.

The invention re.ates to a device for closing and protecting the ends of rolled material such as roofing paper and the like. Such a device commonly consists of a pair of end plates for the roll and a tie rod extending through the bore of the roll and connecting the end plates together. My invention relates more particularly to a novel construction of the tie rod for anchoring the ends thereof to the end plates.

The object of my invention is to provide an improved connection between the tie rod and the end plates, which renders the device economical in the use of materials, capable of being manufactured at a low cost, adapted to be quickly and easily applied to a roll, and rugged and effective in use.

In carrying out my invention, I form the connection between the tie rod and either end 210 plate by splitting the end of the tie rod after passing through the end plate so as to provide an enlargement thereon incapable of passing through the end plate; and I preferably employ, in combination with the end 2 plate, a washer fitting snugly over the tie rod and bearing against the end plate, the latter having an opening of a diameter substantially larger than the diameter of the tie rod, which opening is closed by the washer. By this construction it is possible not only to use a tie rod in the form of a wire of small diameter, but it is also possible to use end plates of relatively thin gage sheet metal. This is advantageous because it reduces the cost of the material, and also reduces the weight of the device, rendering it possible to increase substantially the number of devices contained in a shipment of a given weight. In prior constructions it has been found necessary to employ rods of substantial thickness owing to the methods employed in fastening the rods to the end plates.

In the accompanying drawings, I have illustrated my invention as applied to a tar paper roll in the bore of which is contained a number of packages as is usual in the art, which packages are held in position by means of a tie rod connecting the end plates and placed under tension.

Fig.3 is an end view of the rod on a still larger scale, showing the end of the rod after the same has been cut and bent to provide an enlargement 0nthe end thereof.

Fig. 4 is a side view of one end of a modilied form of the device.

In Fig. 1, the tar paper or other fabric roll 1 has the usual central bore 2 within which are located a plurality of packages 3 containing the usual material such as cement, nails, etc., for use in the application of the rolled material.

The end closing and protecting device comprises a pair of inwardly dished end plates i, centrally apertured at 5 and connected by means of a tie rod 6 having the opposite ends passing through said apertures 5. In the embodiment shown in Figs. 1 to 3, each end of the rod 6 is cut and bent to provide an enlargement in the form of a head 7. The heads 7 at opposite endsot the rod operate to hold the plates firmly against the ends of the roll, preferably through the medium of washers 8 engaging the outer sides of the plates about the central apertures 5. When such washers are used, the apertures 5 are made of a diameter substantially larger than the diameter of the rod 6, and the end plates 85 may be made of a relatively light gage sheet metal.

In practice the end closing and protecting device is usually supplied to the manufacturers of the tar paper roll with the end 90 plates detached. That is to say, the end platesl are assembled in quantities, in nested relation, the tie rods 6 being detached from the end plates. As herein shown, one end of the tie rod is equipped with a washer 8, the 5 washer being heldat that end of the tie rod by means of a head 7 and a widened portion 9 formed by squeezing the rod at a point spaced a short distance from the head 7. The apertures 5 in the plates at are made large enough to pass the widened portion 9 on the rod so that in the assembling of the two end plates and rod in a roll, the rod may be passed first through one end plate shown at the left in 2, and then through the other end plate at the opposite end of the roll.

Th e means employed for forming the split heads 7 may be of any suitable character forming no part of the present invention, and. therefore. not herein illustrated and dcseribed. here the device is shipped to the mannfa etnrer of the rolls for application thereto. the latter will be supplied with a tool whereby, when the rod has been passed through the roll and the end plates at opposite ends thereof with one end anchored in one of the plates, the other end may be seized and, while it is placed under tension, it is cut off to the proper length and then sheared and split or separated to form the other head 7.

As shown in Fig. 3. the splitting of the end of the rod to form the head 7 is accomplished by making a shearing cut diametrically of the rod and the portions on opposite sides of the line of out are bent in a direction parallel to the plane of the cut, forming segmental wings 1O offset with respect to each other. Also these wings 10 are preferably twisted slightly across the plane of the cut, so as to effect an interlocking of the wings in oroer that they may more effectually resist a tendency to swing back into their normal relation under the tension of the rod.

It will be apparent that the heads 7 thus formed. on the ends of the rod serve effectually to hold the end plates tightly against the ends of the roll. Moreover, the construction lends itself to the easy removal of the device from the roll, it being only necessary to force the wings 10 back into their normal relation as by means of a pair of pliers.

Instead of splitting the rod to form two segmental wings 10, one wing 10' (Fig. 4-) may be provided and this wing bent outwardly but in the direction of the roll rather than in the direction away from the roll as in Figs. 1 to 3. The wing 10 is formed by making a diametrical cut in the rod which cut swerves transversely of the rod to form the free end of the wing. The latter is then bent so that its free end is offset relative tothe rod and constitutes an abutment adapted to engage with the washer 8.

While I have herein shown the tie rod at both ends of the roll provided with split heads 7, it will be understood that the invention is not limited to this construction, it being obvious that one end of the rod may be anchored to the corresponding end plate in any preferred way, according to the desires of the manufacturer. In other words, my invention has especial reference to the final operation in applying the device to a roll, namely, the formation of the split head on one end of the rod after it has been passed through the roll and both of the end plates.

1 claim as my invention:

1. An end closing and protecting device for a fabric roll comprising a pair of end plates adapted to engage opposite ends of the roll. and a tie rod having one end anchored to one of the end plates and its other end passing through the other end plate and proiecting a short distance therefrom, said projecting portion of the tie rod being split to provide two portions, one of which is bent into interlocking relation to the other to form an enlargement engaging with the outer side of the last mentioned end plate and acting to hold the rod under tension.

2. An end closing and protecting device for a fabric roll comprising a pair of end plates adapted to engage opposite ends of the roll, and a tie rod having one end anchored to one of the end plates and its other end passing through the other end plate and projecting a shortdistance therefrom, said projecting portion of the tie rod being sheared substantially diametrically thereof with the sheared portions bent in opposite directions substantially in the plane of the line of shear so as to form an enlargement adapted to engage with the last mentioned end plate and acting to hold the rod under tension, said bent portions being twisted relative to each other into interlocking relation.

In testimony whereof, I have hereunto affixed my signature.
